Description

The utility model relates to the working bodies of tillage machines, in particular to the working bodies of disk harrows, disk drives.

Known cut-out spherical disks, each of which has its own rack and its own bearing assembly ("Modern resource-saving technologies. - Krasnodar: Specialized, information-analytical newspaper" Agro-Tech-Inform. - 2009, No. 1 - S. 9).

The disadvantages of the known technical solutions that impede the achievement of the claimed technical result are high energy costs per revolution of the undercut soil.

Known slotted smooth spherical discs with radial trapezoidal windows. The larger base of each window faces the cutting edge of the disc (Copyright Certificate SU No. 1358798, publ. 15.12.1987).

The disadvantages of the known technical solutions that impede the achievement of the claimed technical result are insufficient soil wrapping and poor quality of crumbling due to the trapezoidal shape of the windows.

For the prototype, the working body of the disk tools was selected, in the form of a spherical smooth or cut-out disk, each of which has its own stand and its own bearing assembly, the disk is made with perforation around the perimeter in the form of a circle with a symmetrical offset from the cuts, installed on the back of the disk in the perforation zone Chistik (application for invention No. 2009147583, publ. 06/10/2010).

A disadvantage of the known technical solution that impedes the achievement of the claimed technical result is the reduction in the bore of the perforation holes when the disk is mounted at the optimal angle of attack and inclination to the vertical-longitudinal plane of the rack.

The task is to perform the optimal passage section of the perforation holes, taking into account the installation of the disk at the desired angle of attack and inclination to the vertical-longitudinal plane of the rack.

The technical result is an increase in soil throughput through perforation holes with a simultaneous improvement in performance and improving the quality of tillage.

The claimed technical result is achieved by the working body of the disk implements in the form of a spherical disk, each of which has its own stand and its own bearing assembly, perimeter perforation in the form of a circle with symmetrical displacement from cuts is made on the disk, scrapers are installed on the reverse side of the disk in the perforation area, edges the perforation holes are made with sharpening, while the passage sections of the perforation holes are made taking into account the installation of a spherical disk at the desired angle of attack and inclination to a vertically longitudinal plane STI stands.

The essential features affecting the achievement of the claimed technical result is:

- the implementation of the edges of the perforation holes with sharpening;

- the implementation of the through section of the perforation, taking into account the installation of a spherical disk at the desired angle of attack and tilt to the vertical-longitudinal plane of the rack.

Increasing the throughput of the soil through the perforation holes with a simultaneous improvement in performance and improving the quality of the soil treatment occurs due to:

- better mixing of the cultivated soil layer, achieved by performing through sections of perforation holes, taking into account the installation of a spherical disk at the desired angle of attack and inclination to the vertical-longitudinal plane of the rack (i.e., a part of it wakes up through the perforations without rising to the surface and additional crumbling of soil about the edges of the holes.);

- better calibration - the implementation of the edges of the perforation holes with sharpening, the size of the holes corresponds to an allowable number of agrotechnical indicators for this treatment (in particular 50 mm).

A utility model is illustrated in FIG. 1, FIG. 2 and FIG. 3.

In FIG. 1 shows the working body of disk tools.

In FIG. 2 shows a spherical disk taking into account the angle of inclination to the vertical-longitudinal plane of the rack.

In FIG. 3 shows a spherical disk taking into account the installation of the disk at the desired angle of attack.

The working body of the disk tools (Fig. 1) consists of a spherical disk 1, rack 2, bearing assembly 3, perforation 4, cutouts 5, scrapers 6.

An example of a specific implementation.

The technological process of soil cultivation by the proposed working body is as follows.

During operation, disk 1 rotates under the influence of a soil reaction. The movement of disk 1 in the soil occurs along a complex path in the form of a cycloid. Rotating, the disk 1 cuts the soil with its cutting edge, while the concave surface of the disk 1 crumbles and rotates the soil layer. The edges of the perforation holes 4 are made with sharpening. To increase the throughput of the perforation holes 4, without increasing their geometric dimensions, they have a shape that takes into account the slopes of the optimal angle of attack a of the disk 1 and the inclination to the vertical-longitudinal plane of the rack b. Each disk 1 has cutouts 5 around the perimeter and is mounted through the bearing assembly 3 to the rack 2. On the reverse side of the disk 1, scrapers 6 are installed to clean the adhering soil.

Thus, the claimed technical solution in the form of a working body of disk tools, which is made in the form of a spherical disk, each of which has its own stand and its own bearing assembly, perforation around the perimeter in the form of a circle with a symmetric offset from the cuts from the back of the disk scrapers are installed in the perforation zone, the edges of the perforation holes are sharpened, while the passage sections of the perforation holes are made taking into account the installation of a spherical disk at the desired angle of attack and inclination to vert the infra-longitudinal plane of the rack provides an increase in the throughput of the soil through the perforation holes while improving operational performance and improving the quality of tillage.
